   2
   3 Required properties:
   4
   5 - compatible:   must be "maxim,max8973"
   6 - reg:          the i2c slave address of the regulator. It should be 0x1b.
   7
   8 Any standard regulator properties can be used to configure the single max8973
   9 DCDC.
  10
  11 Optional properties:
  12
  13 -maxim,externally-enable: boolean, externally control the regulator output
  14                 enable/disable.
  15 -maxim,dvs-gpio: GPIO which is connected to DVS pin of device.
  16 -maxim,dvs-default-state: Default state of GPIO during initialisation.
  17                 1 for HIGH and 0 for LOW.
  18 -maxim,enable-remote-sense: boolean, enable reote sense.
  19 -maxim,enable-falling-slew-rate: boolean, enable falling slew rate.
  20 -maxim,enable-active-discharge: boolean: enable active discharge.
  21 -maxim,enable-frequency-shift: boolean, enable 9% frequency shift.
  22 -maxim,enable-bias-control: boolean, enable bias control. By enabling this
  23                 startup delay can be reduce to 20us from 220us.
